DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 394,873, dated December 18, 1888. Application led July l0, 1888. Serial 170,279,577. (No model.)

To /LZZ 107mm it may concern:

Be it known that I, EDWARD Y. MOORE, a citizen of the llnited States, lresiding at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Door-Hangers, of which the lfollowing is a speciiication.Y

In a door-hanger charz'tcterized by my invention the sheave or grooved wheel is loosely mounted upon a short axle, which is in turn supported within and adapted to tra\v'ersc a pair of oppositely-arranged guideways. One or both, but preferably both, of the guideways have their terminal portions adapted to bind upon and hold the axle against rotation when the axle arrives at either end of the guideway. In this way, while the axle may, so long as it remains at such point, be held against rotation, the sheave will be free to turn upon the axle, which will serve, therefore, to provide for the sheave a straight cylindrical bearing. l-iy such arrangement the wear incident to the abutment of an axle rigid with the sheave against stops at the ends of ways, as heretofore constructed, is avoided, and, furthermore, a freer rotation of the sheave is permitted, it being evident that an axle rigid with the sheave cannot turn as freely at the end corners of a pair of ways as the sheave will turn upon a stationary axle, and also that according to the old mode of construction it has been a matter of some difiiculty to adapt the ends of the ways to provide a perfectly true bearing for an axle, which must turn at said ends of the ways in I order to permit the rotation of the sheave.

The ways for the axle or journals of the sheave are formed along bars which are shouldered at points adjacent to their terminal portions and at their terminal portions secured to the yoke, so as to bring their shoulders in abutment against the 'inner edges of the yoke, The yoke is provided with bends at its ends, and the said bars are attached to the outer sides of what may be termed the short legs of the bends, in which way the yoke may be provided with comparatively short bends at its end portions, thereby affording greater strength, rigidity, and durability than where the application of the bars has necessitated the employment of comparatively long bends at such points.

Further details of construction, which likewise increase the general efficiency and utility of the hanger, will be more readily understood by reference to the drawings, in which- Figure l represents in side elevation a door-hanger constructed in. accordance with my invention. Fig, 2 represents a section taken transversely through Fig. l on the line 2 2. Fi 3 represents a section taken through Fig. l on a horizontal plane indicated bythe line 3 3. Fig. 4 is a detail showing in .top plan an end portion of one of the bars B and in cross-section the short leg of the yoke, to which such bar is secured. Fig. 5 represents in side elevation one of the guideways having converging top and bottom walls.

The yoke A is at its ends provided with the bends o, one for each end portion of the yoke. The bars B are secured to the short legs a of said bends, and are channeled to provide a pair of oppositely-arranged parallel guideways, wherein the end portions of an axle, c, for the sheave C are received and supported. The sheave is loosely mounted upon the axle, which may freely roll along the channels or guideways, excepting at the ends of the latter, and at each of such points a certain contraction occurs in either or both of the guideways or in the relative arrangement of the two, in which latter case the two maybe, and, in fact, are, as a whole, a guideway for the axle. Iith reference to the contraction of the guideway, considering it to be combined of the two channels, the oppositelyarranged vertical back walls, b, of the channels converge toward their terminals, as indicated by the shading in Figs. l and :2, but best represented in the section shown in Fig. By reason of the converging portions b of the back walls of the guideways the. axle will upon reaching either end of its allotted extent of travel wedge between the oblique or converging portions of the guideway, and hence be held against rotation. The sheaves can, however, rotate freely upon the axle, so that while the axle may be wedged between the converging portions of the back walls of the guideways it will provide a straight cylindric bearing whereon the sheave may turn.

The horizontal iianges b2, which serve to` provide the top and bottom walls of the guideways, terminate short of the ends of the bars IOO B, and at their points ot' termination are pro vided shoulders which abut against the inner edges ol' the yoke, thereby bracing the yoke and insuring a l'irm eonneetion between the yoke and the guidefbars 13.

'lhe flat terminal portions Ui of the bars B are applied against and riveted to the outer sides oit' the legs a ot' the V-ben ds in the yoke, thereby shortening;l up the bends and bringing,I the legs oi' each bend comparatively elose together. This construction, while affording,l greater strength at the bends, also permits the formation of hoi-izontally-deeper ehannels, whereby the bottom sides or walls if? may be comparatively wide, and hence afford broad bearilig-surl'aees :for the axle to rollv upon.

The top and bottom flanges lf3 o'l the bars are at their ends tlanged transversely, or respectively turned up and down, as at'. b, lfi il, wherein one of the bars `is broken away, so as to represent the aforesaid Construction at one end of the tianged portion ot' the bar, which is thus exposed to view. Said flanged portions D et' the hars ean be strengthened by longitudinal ribs tr", whieh also strengthen the bars.

In Fig. 5 one of the ehanneled bars is shown having the top and bottom walls 'U2 ot' its channel arranged to converge toward the ends of the Channel. By this arrangement the walls will bind upon the axle when the latter reaches the end of the channel, as indicated in dotted lines. llenee either the vertieal opposing walls of the two chan nels may converge toward one another or the horizontal walls ot' either or both channels may eonverge, as in Fig. 5, or both oi' sueh eonstru the sheave and an axle whereon the sheave is loosely mounted, ol a euideway t'or the axle havin a cont'ratd'ed end portion, whereby the axle upon arrivingI at such point shall wedge in the eontrusted portion to an extent to arrest and holdV it, but permit the free rotation of the sheave, substantially as set lforth.

2. ln a door-hanger, the emnlanat'ion, with the sheave loosely mounted upon an axle, ol a pair of oppositely-arranged channeled bars having' converging walls at their end port ions to bind upon the axle, as and l'or the purpose described.

Il. ln a dma-hanger, the eomliinat'ion, with the yoke A, oit' the bars provided with llzulg'es W, whieh 'terminate short ot' the ends ot the said bars and abut against the inner edges olf the yoke, the terminal portions D of the bars being` secured to outer sides ot the legs oll the bent end portions of the yoke, substantially as and t'or the. purpose described.

el. AIn a door-hanger, the eombination, with the yoke A, olf the bars l, provided with horizontal lflanges 112, and the shortvertieal l'liulges tf1 at the terminals ot' the said horizontal flanges, substantially as deserilunl.
